The Complete Property Due Diligence Checklist

50+ items organized by phase: pre-offer, under contract, before closing, and post-closing. Never miss a critical step.

Due diligence is the process of verifying every material fact about a property before you commit to buying it. Skipping steps or rushing through diligence is the single most common cause of bad real estate investments. This checklist organizes 50+ items into four phases. Print it, save it, and use it on every deal.

Phase 1: Pre-Offer (Before You Submit an Offer)

This phase is about determining whether the deal is worth pursuing. You should be able to complete these items using publicly available data and a brief property visit.

Market Analysis

  • Population trend: Is the metro area gaining or losing residents? Check U.S. Census Bureau data and state demographic reports. Growing markets support appreciation and rent growth; declining markets carry higher vacancy and depreciation risk.
  • Job growth: Are major employers expanding, stable, or downsizing? Bureau of Labor Statistics (BLS) data and local economic development announcements are key sources.
  • Median household income: Is the area's median income growing? Stagnant or declining incomes limit rent growth potential.
  • Crime data: Check local police department crime maps and NeighborhoodScout or CrimeMapping.com. High-crime areas correlate with higher vacancy, lower rents, and higher insurance costs.
  • School ratings: GreatSchools.org ratings affect tenant demand and rent premiums. Properties zoned for highly rated schools command 5-15% higher rents in many markets.
  • Insurance environment: Is the area experiencing insurance cost increases or carrier exits? Check our Insurance Crisis Dashboard. In some Florida and Louisiana markets, insurance costs have doubled or tripled since 2020.
  • Landlord-tenant law: Research state and local eviction timelines, rent control laws (if any), security deposit limits, and notice requirements. Some jurisdictions take 6-12 months for an eviction; others take 3-4 weeks.

Property-Level Analysis

  • Comparable sales (comps): Pull 3-5 comparable sold properties within 0.5-1 mile, similar size/age/condition, sold in the last 6 months. Verify the asking price is at or below market value.
  • Comparable rentals: Pull 3-5 comparable active or recently rented listings on Zillow, Apartments.com, or Rentometer. Verify your projected rent is achievable, not aspirational.
  • Property tax records: Check the county assessor for current assessed value, annual tax amount, and any pending reassessment triggers. In some states, the property tax resets to the purchase price upon sale.
  • Flood zone check: Verify the property's FEMA flood zone at msc.fema.gov. Flood insurance can add $500-$5,000+/year. If the property is in Zone A or V, factor this into your proforma.
  • Zoning verification: Confirm the property is zoned for your intended use. If you plan to add an ADU, operate a short-term rental, or convert to multifamily, verify zoning allows it.
  • Preliminary proforma: Run a full proforma with conservative assumptions. Does the deal meet your minimum cash-on-cash return threshold (typically 8-12% for buy-and-hold)? If not, move on.
  • HOA rules and fees: If applicable, request the HOA's CC&Rs, financial statements, and meeting minutes. Verify rental restrictions (some HOAs limit or prohibit rentals) and upcoming special assessments.

Drive-By / Initial Visit

  • Neighborhood condition: Drive the neighborhood at different times (morning, evening, weekend). Look for vacancy rates, property maintenance levels, and overall feel.
  • Exterior condition: Roof (age, visible damage), siding, foundation (cracks, settling), drainage (grading away from house), landscaping, fencing.
  • Parking and access: Adequate parking for tenants? Easy street access? Any easement or right-of-way issues?

Phase 2: Under Contract (After Your Offer Is Accepted)

This is the most critical phase. You have an accepted offer and an inspection/due diligence contingency period (typically 7-14 days in most markets, though this varies). Use every day of this period.

Professional Inspection

  • General home inspection: Hire a licensed inspector ($350-$500 for a typical SFH). Attend the inspection in person. Pay attention to: roof age and condition, HVAC age and function, electrical panel (breaker type, capacity), plumbing (material, water pressure, water heater age), foundation, windows and doors, insulation, ventilation.
  • Sewer scope: $150-$300. Especially important for older homes (pre-1970). A collapsed or root-damaged sewer line can cost $5,000-$15,000+ to repair. This is one of the most cost-effective inspections you can add.
  • Pest/termite inspection: $75-$150. Required by many lenders. Look for active infestation and prior damage. In the Southeast, termite damage is extremely common in older homes.
  • Radon test: $150-$200. Recommended in all markets but especially the Midwest and Northeast where radon levels are commonly elevated. Mitigation costs $800-$1,500 if needed.
  • Mold inspection: If visual signs of water damage or musty odors are present. $300-$600 for professional testing.
  • Lead paint assessment: Required disclosure for homes built before 1978. If children will occupy the unit, consider professional testing ($300-$500).

Appraisal

  • Lender-ordered appraisal: Your lender will order this ($400-$600). Review the appraisal report for accuracy: correct square footage, bedroom/bathroom count, and comparable sales used.
  • Appraisal gap: If the appraisal comes in below your purchase price, you must negotiate (price reduction, appraisal gap coverage, or walk away). Do not overpay relative to appraised value unless you have a specific strategic reason.

Title and Legal

  • Title search and title insurance: Your title company or attorney will search for liens, judgments, easements, and ownership disputes. Always purchase owner's title insurance (lender's title insurance is separate and typically required by your lender).
  • Survey: Not always required but recommended, especially for properties with unclear lot boundaries, fences, or structures near property lines. $300-$600.
  • Review deed and legal description: Verify the legal description matches the physical property. Check for easements, encroachments, or deed restrictions.

Insurance

  • Get insurance quotes: Obtain at least three DP-3 landlord insurance quotes. Include loss of rent coverage and sewer backup endorsement. Factor the annual premium into your proforma.
  • Flood insurance quote: If in or near a flood zone, get both NFIP and private flood quotes.
  • Verify insurability: In some markets (coastal Florida, fire-prone California), some carriers will not write new policies. Confirm you can get coverage before you close.

Financing

  • Lock your rate: If you have not already, lock your interest rate during the under-contract period. Rate locks typically last 30-60 days.
  • Verify loan terms: Review the Loan Estimate for accuracy: interest rate, points, closing costs, escrow requirements, prepayment penalties (if any).
  • DSCR verification: If using a DSCR loan, confirm the lender's DSCR calculation matches yours. Some lenders use gross rent; others use net rent. This can change your qualification.

Property Management

  • Interview PMs: If using professional management, interview at least two PMs during the under-contract period. Compare fees, services, and references. Have a PM selected before closing.
  • Review PM agreement: Have your attorney review the management agreement before signing.

Tenant Verification (If Buying with Existing Tenants)

  • Review existing leases: Verify lease terms, rent amounts, security deposit amounts, and expiration dates.
  • Verify rent roll: Request proof of rent payment history (bank statements or PM ledger) for the past 6-12 months.
  • Estoppel certificates: Have each tenant sign an estoppel certificate confirming lease terms, rent amount, security deposit held, and any claims or disputes.
  • Security deposit transfer: Ensure security deposits are transferred to you at closing and comply with state law for deposit handling.

Phase 3: Before Closing (Final 3-7 Days)

  • Final walkthrough: Walk the property 1-2 days before closing. Verify condition matches what you inspected. Confirm all negotiated repairs are completed. Check that all appliances, fixtures, and systems are in working order.
  • Verify utilities: Contact utility providers to transfer service to your name (or PM) effective on the closing date. Water, electric, gas, trash, sewer.
  • Set up bank accounts: If using a dedicated LLC or property account, open the bank account before closing so you have a place to deposit rent and pay expenses immediately.
  • Review closing disclosure: Compare the Closing Disclosure to the Loan Estimate. Verify all numbers match within TRID tolerance limits. Question any unexpected fees.
  • Wire transfer preparation: Verify wire instructions directly with the title company (call them at a known phone number, not from an email — wire fraud is rampant). Prepare funds for wire transfer 1-2 business days before closing.
  • Insurance binder: Confirm your insurance policy is bound and the declaration page has been sent to your lender and title company.
  • Bring to closing: Government-issued photo ID, certified funds or wire confirmation, proof of insurance, any documents your lender or title company has requested.

Phase 4: Post-Closing (First 30 Days)

  • Record the deed: Your title company should record the deed with the county. Verify recording within 2-4 weeks.
  • File for homestead exemption: If applicable (owner-occupied or in states where investment property qualifies for certain exemptions).
  • Notify tenants: If buying with existing tenants, send a formal written notice of ownership change, new rent payment instructions, and maintenance contact information. Include security deposit acknowledgment per state law requirements.
  • PM onboarding: If using a PM, complete onboarding: transfer keys, alarm codes, appliance manuals, tenant files, vendor contacts, and reserve funds.
  • Set up accounting: Create a property file in your accounting system (Stessa, QuickBooks, or spreadsheet). Record the acquisition cost, closing costs, and any immediate expenses as your cost basis.
  • Document everything: Photograph the property interior and exterior for your records. Save all closing documents, inspection reports, insurance policies, and warranties in a dedicated folder (cloud storage recommended).
  • Update your proforma: Now that you have actual numbers (purchase price, closing costs, insurance premium, property tax), update your proforma from projected to actual. This is your baseline for tracking performance.
  • Set calendar reminders: Lease expiration dates, insurance renewal dates, property tax due dates, annual inspection dates (if Section 8), and PM contract review dates.
  • Review with your CPA: Discuss depreciation schedules, cost segregation eligibility, and estimated tax impact with your accountant. Ensure the property is properly categorized for tax purposes.

The Most Commonly Skipped Items

Based on investor experience and deal post-mortems, these are the items most frequently skipped that lead to expensive surprises:

  1. Sewer scope: A $200 inspection that prevents a $10,000+ surprise. Get one on every property over 20 years old.
  2. Insurance quotes before offer: In Florida and Louisiana especially, insurance can add $3,000-$8,000/year to your expenses. Get quotes before you offer, not after.
  3. Flood zone verification: A property one block from a flood zone may still flood. Check the FEMA map.
  4. Estoppel certificates: Buying with tenants who claim different lease terms than the seller represented can create immediate disputes.
  5. PM interview before closing: Scrambling to find a PM after closing leads to poor selection and delayed rent collection.
  6. Property tax reassessment: In many states, the tax resets to the purchase price. Your proforma based on the seller's lower tax bill will be wrong.
